Function bdblib_create_table

modules/db_berkeley/bdb_lib.c:560–712

* The function is called to create a handle to a db table. * * On startup, we do not create any of the db handles. * Instead it is done on first-use (lazy-initialized) to only create handles to * files (db) that we require. * * There is one db file per opensips table (eg. acc), and they should exist * in your DB_PATH (refer to opensips-cli) directory. * * This function does _not_ create t
